What is an ICO file, and why convert to it?
ICO is the Windows icon format and the classic format for a website favicon. Unlike a single PNG, one .ico file can hold several resolutions at once, so the operating system or browser picks the sharpest size for each context. Converting your PNG to ICO gives you a proper icon for a favicon, desktop shortcut, or application.
Which icon sizes should you include?
16px and 32px cover browser favicons and tabs; 48px is used in the Windows taskbar and file lists; 256px keeps the icon crisp on high-DPI displays. Including 16, 32, and 48px suits most websites, and adding 256px future-proofs the icon for larger contexts.
Is this PNG to ICO converter free and private?
Yes. It's completely free with no signup, and the .ico is assembled entirely on your device — your PNG is never uploaded.
Frequently asked questions
- Can I use the .ico as a favicon?
- Yes. Download the .ico, place it in your site root as favicon.ico, and most browsers will pick it up automatically.
- Does the icon keep transparency?
- Yes. Each size is stored as a 32-bit PNG inside the .ico, so transparent areas of your PNG stay transparent.
- Do you upload my PNG?
- No. The .ico is built locally in your browser — your file is never uploaded, stored, or seen by us.
